Having read the STUN operation (contributed by Wayne Clark) and other related
mail replies, I have the following questions:

1. Why is it better to hold u-frame responses that are destined to the
   primary until there is a retransmission of the u-frame command.
   Could some one explain the timing problems if any. Are these problems
   an implementation specific problem ?

   Is'nt the above mechanism missing in DLSw ?.

2. How does throttling SNRMs avoid time out problems if there are
   end-to-end network delays ?. Is there a basis for choosing 5s as the 
   throttling rate.

3. Does the STUN group need to be a part of the frame sent to the
   destination IP router ?. If not how does the destination router identify
   uniquely when there are duplicate SDLC addresses ?.
